1. Lubricity: Calcium stearate powder acts as an effective lubricant by reducing friction between particles. When added to plastic or rubber compounds, it helps in improving flowability and preventing sticking or agglomeration during processing.

2. Demoulding Performance: Calcium stearate has excellent demoulding properties, making it useful in manufacturing processes where removing products from molds or dies is necessary. It reduces adhesion and facilitates easy release of finished products from molds.

3. Stability: It exhibits stability at high temperatures, which makes it suitable for applications that involve processing at elevated temperatures, such as extrusion or injection molding.

4. Anti-Caking Agent: Calcium stearate powder also functions as an anti-caking agent, preventing the formation of lumps or clumps in powdered formulations. This property ensures consistent and uniform dispersion of the powder.

5. Compatibility: It is compatible with various polymers, including PVC, polyethylene, and polypropylene, making it versatile and widely used in the plastics industry.

6. Cost-Effective: Calcium stearate is relatively inexpensive compared to other lubricating additives, offering a cost-effective solution for improving processability and product quality.
